Which filter cup is better to use for hand-brewed coffee? What are the characteristics of making coffee with ice pupil filter cup?

V60 filter cup, one per capita civilian filter cup, its performance can be said to be "everyone said yes". But. "it doesn't stick to the filter cup."

(complain: don't be black, it's obviously your technical problem.) "this time it really doesn't fit, and some of it is so tight that the ribs can't stand up."

"what's more, the filter paper is sticking out, and it looks uncomfortable!"

For this kind of users with requirements, there is really a filter cup suitable for this kind of users, which is the "ice pupil".

This filter cup does not look very special, and its appearance is very similar to that of V60, but when you put the filter paper on it and wet it, you will be amazed: "this is perfect!"

In terms of height, it's just right.

In fact, after careful observation, the ribs of V60 are protruding threads, and the filter paper is supported by these ribs, while the ice pupil filter cup is on the contrary, its filter cup wall is very thick, and its "ribs" are actually concave grooves set off like "protruding" ribs. The "protruding" ribs and the top laminate layer belong to the same plane, so they fit well.

As an experienced V60 user, almost all coffee beans can be solved with V60, so one of the biggest impressions (highlights) of this filter cup to the front street is the super comfortable filter paper filter cup. Regardless of its extraction function, just from this point of view, it is enough for the front street to start one (anyway, the resin version is not expensive). Next, let's see if this filter cup is easy to use. the performance of the filter cup in front of the street is relatively simple. The first point is the diversion tank design, and the second point is the launching speed. The design of the diversion trough mainly depends on the influence of its morphological characteristics on the extraction, such as the threaded guide bone of V60 and the multi-linear guide bone of the star, which play a different role in guiding the flow.

The index of launching speed is not based on extreme speed, but mainly on the filter cup choices made according to the different properties of beans. For example, the short bone version of Kono, which is relatively slow in flow, is suitable for brewing some mellow deep-roasted coffee beans. If you want to express light and lively coffee, use a filter cup with a faster flow rate. The structure of ice pupil filter cup is divided into three parts. Side view is that the height is divided into three. The uppermost rib-free structure has a smooth wall, similar to the Kono filter cup. The middle layer and the lower layer are no longer raised rib support filter paper, but a large area of sunken structure, affixed with filter paper, seems to be composed of 12 long ribs and 12 short ribs (in fact, these 'ribs' are in the same plane as the upper layer), distributed in a straight line, 'short ribs' are distributed in the middle layer, and 'long ribs' in the middle and lower layers.

When brewing, because the filter paper at the top of the filter cup is completely sealed, then if the water flow is too much and the water temperature is too high to flood the diversion tank, but because there is no room for exhaust, the falling rate of the water level will slow down and can be soaked like a KONO filter cup to avoid insufficient extraction. The grooves in the middle and lower layers can quickly guide the flow down and avoid blockage. Such a design is actually equivalent to having a safety lock. When the water level is relatively high, the V60 is to "clear the channel and guide quickly." The ice pupil is "the door is closed tightly to reduce leakage." When the water level is low, the launching speed of the ice pupil is slightly faster than that of V60.

When brewing coffee with ice pupil, as long as the current is stable and straight, it is generally easy to achieve uniform extraction of coffee powder layer. In fact, there will not be much difference in the flavor performance, coffee beans determine the flavor, the filter cup is not good or bad, only whether it is suitable or not.
